Bag type dust-collecting, energy-storing ash-removal method

Abstract

The invention relates to a bag type dust-collecting, energy-storing ash-removal method. The method comprises the following steps: a cloth bag group is hung on a roof plate of a box body, and a spring with a pretightening force is arranged below the cloth bag group; then an external force is slowly applied to up and down directions to store energy on the spring; and when the external force is applied to a certain degree, a mechanism is released suddenly, the cloth bag group obtains the energy to generate speed jump so as to realize ash removal. The energy is stored on the spring by using a very small external force; when released, the spring is bounced out at a very high speed; an acceleration of more than 300m / s<2> is not less than that of a pulse, therefore, the ash is thoroughly removed; the removed dust does not influence adjacent cloth bags; the cloth bags are not shortened or elongated, shrunken or expanded, the service life of the cloth bags is not affected; compressed air is unneeded; the energy consumption is 1 / 10 or even less of the pulse energy consumption; the cloth bags have simple structure, firmness and durability and no maintenance or easily damaged parts; and a bag cage is unneeded when an inner filtering mode is used; and the ash-removal effect is superior to that of all of the current ash-removal methods.

Description

technical field [0001] The invention relates to a dust removal method for a dust collector, in particular to a bag dust removal storage energy dust removal method. Background technique [0002] Existing bag-type dust collectors are divided into three categories according to the cleaning method, one is the mechanical vibration and rapping category, the other is the fan back suction and blowback category, and the third is the compressed air pulse category; the first category is simple in structure but clean. The ash effect is poor; the effect of the second type is general; although the effect of the third type is the best, it is prone to failure due to a large number of pulse valves and blowing pipes, and the dust is washed to the adjacent cloth bag when cleaning the dust, and the cost is high. , high energy consumption and other defects. [0003] Among all the current bag-type dust collectors, some have only upper flower boards, some have only lower flower boards, and some h...

AI Technical Summary

Problems solved by technology

There are serious defects in this dust cleaning method: because the flower board is fixed, the lower head of the cloth bag must also be fixed. When cleaning dust, the cloth bag must also be stretched and shortened countless times, thus greatly shortening the service life of the cloth bag; The range of length and shortening is very small, generally less than 50 mm, so the cleaning frequency is high. Once the range increases, the life of the bag is only dozens of days

In all the cleaning methods at present, the bag is either stretched and shortened or expanded and contracted without exception, thus affecting the life of the bag

[0004] The designer of this patent mentioned a kind of dust removal mechanism in the patent application whose application number is 2009101350321, and mentioned another kind of dust removal device in the patent application whose application number is 2009101653409. These two mechanisms are all limited by their own structure , cannot be widely used
